BRUSH,

Application led August 2, 1924. Serial No. 729,803.

T0 all whom z't may concern.'

Be it known vthat I, VICTOR Knilinowskr, a citizen of Poland, residing at South Chi cago, county ofl Cook, and State of Illinois, have invented certain new land useful Improvements ina Brush, of which the following is a specification. v

My present invention relates to brushes, and more particularly to brushes, especially gill adapted for use in cleaning pots or the The primary object of the invention is to provide an improved brush embodying features wherebv the brush head may be disposed in various ositions with respect to the handle of the rush.

A further object of the invention is to provide an improved brush embodying features whereby should the brush head become worn so as to render it unfit for further use, the same may be readily removed and a new one substituted therefor upon the original handle of the brush.

A still further object is in the novel construction of the brush whereby a material saving of wood will be had, since the handle portion of the brush which is preferably made of metal, may be readily associated with the wooden brush head block, thereby eliminating the use of the usual wooden handle portion which, since it constitutes a portion of the brush head, must be discarded when the brush becomes worn out.

Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification and in which drawing Figure 1 is a perspective view of a brush constructed in accordance with my invention;

Fig. 2 is a central longitudinal section through the same and showing the brush head in a reversed position after the forward bristles have become worn;

Fig. 3 is a sectional view taken on the line 3-3 oil Figure 2, looking in the direction of the arrows;

Fig. 4 is a sectional view take on line Llof Figure 3, `looking in the direction of the arrows; and

Fig. 5 is a bottom plan view of the improved brush head block showing the general appearance thereof before the bristles have been secured thereto.

' Referring to the drawing in detail, and wherein similar reference characters designate corresponding parts throughout the sev- 'eral views, the letter' A may generally designate my improved brush comprising a handle portion B; a brush head C, and means D for retaining the brush head C in adjusted relation to the handle portion B.

Referring to the handle portion B, which is preferably formed from sheet metal, the i.

same embodies a handle. 10 which may be formed by: rolling the metal into tubular formation, and at the forward end of which is formed a substantially flat square head plate 11 having depending side plates 12 formed at its longitudinal edges.` These side plates 12 are bent inwardly at a point intermediate their upper and lower edges for providing inwardly extending tongues or guides 13 which extend longitudinally throughout the entire length of the side plates. The rear end of each side plate 12 has a portion bent inwardly at right angles to the side plates7 for forming stops 111 which are adapte-d to limit the inward movement of the brush head C when being positioned in the handle portion B.

The brush head C comprises a head 15 which is preferably square shaped in plan, and to the substantially convexed bottom face 16 of which divergingly arranged bristles 17 are attached in any suitable manner desired. Each of the four side walls 18 of the head 15, which are preferably of a height equal to that of the side Aplates .12, are provided intermediate their upper and lower marginal edges with longitudinally extending grooves 19 which communicate one with another at the marginal end portions of the side walls. The top face 2O of the head 15 is flatin order that when the brush head C is positioned in the handle portion B, the top face of the head will lie in surface contactwith the lower face of the flat head plate 11 for reinforcing the same and also permitting of the proper functioir ing of the retaining means D with respect to the brush head C. 4

,Referring to the means D for retaining the brush head C in adjusted relation upon j face 2O of the head 15. O'Wing to the relatively thin sheet vmetal of which thefhandle portion may be constructed, a nut orbearing block 24 having a screw threaded bore, is preferably welded or otherwiseseeured coaxially ot' the outer tace of the head plate l1 for providing a substantial bearing i'or the shank of the thiinib screw.

During the use oi the ordinary type ot brush for cleaning pots or the like, the ferwardly inclined bristles oi the brush head loeoomo Worn ver shorty While the roar bristles .oi the brush show little or no wear. llilhen these forward bristles become worn to an appreciable degree, the brush is op dinarily discarded because .Of .the fac-t vthat it is impossible to use the brush for eifectively cleaning in the corners of the pots or pans.

By so constructing the brush as disclosed, an arrangement will be had whereby iour diiierent positions oi' the brush headmay be had with respect to the handle of the brush, thereby permitting the nnworn bristles et the brush head to be disposed in a forwardly inclined position with respect to the handle portion. ThisV is clearly illustrated in Figure 2 of the drawing. This construction not konly permits of the entire using up of the bristles oit the brush head, but also permits oit a new brush head to be readily associated with the original handle portion of the brush.

After the forwardly inclined bristles of the brush head have become worn to an ex tent where they cannot be Jforced into the corners oi a pot for thoroughly cleaning the same, the thumb screw 21 may be turned free of the recess 23, for permitting of the brush head to be ,drawn forwardly .out- `of the handle portion B. vThe brush head may then be turned to the desired position and slid back into the handle portion with the longest bristles foremost o1" the brush. Since the head l5 is square shaped in plan, and has the grooves 19 provided in each side wall thereof, it Vcan be seen that the brush head may be slid into the handle portion in any one oi four ositions vThe stops 14 serve as means for al igning the recess 23 in a position for receiving` the shank of the thumb screw 2l which is adapted to be turned into the recess for preventing withdrawal otl the brush head :from the handle portion ont the brush.

From the foregoing description of this invention, it is obvious that a blfLlSh has been provided embodying novel features :of ccnstruction, and possessing practical merit, in that the same will permit yof the .entire using up of the bristles of the brush, due to the rr'ongement whereby the brush hood may be dlsposed at various positions with respect to the handle portion.

Various .changes in the shape, size and arrangement ci parts may be made to the form of the invention herein shown and described, without departing from the spirit of the invention ortho scope of the claims.

I claim: l

l. A brush comprising a handle, a head plate atene end of saidhandle,havingder pending oido walls formed at 'the longitudiiial'odees thereof .and provided intermediate their oppor ondlowor edges with inwardly extending guides extendi'n 'longitudinally throughout tho. .length of Sido Walls, a removable and reversible brush hood oo111- prising a head portion' having a face and side walls and bristles extending from said face, oooh of said sidewalls bongpl'ovdod with longitudinally extending grooves 'for sliding intel-fitting relation with ,Said saldos of the head plato, and Y for retaining the brush head in the headplate and in tle desired adjusted relation with respect to 'said handlo- 2- A brush comprising a handle, a hood plate at one end 'thereof having 'depending Sido walls formed at tho longitudinal Sido edges thereof and provided with ,inwardly struck guides extending 'longitudinally throughout the length `ofthe -side walls, la removable brush head for the head plate olphodyng a head portion boing' square Shaped in plan and having a Centrally' dS- posed recess .provided hi the oppor' face thereof and with oooh of .the oor ,Sido walls of Sold head provided with longitudinally extenda grooves extending thron hout tho length o the Walls, bristles optondlne ,from said head, and a set screw threaded Vdown- Wardly through Said hoed plato and .adapted to have .tho 'shank portion thereof turned into `the recess in the up er face ofsaid head whereby the brush hea( will be retained in adjusted relation ,with Said handle 3.
